Abstract
The present invention provides a method and device for transmitting/receiving an uplink signal. When an Scell group including only Scells is set for a user equipment of the present invention and one of the Scells included in the Scell group is set as a cell (hereinafter, “Acell”) in which a PUCCH can be transmitted, UCI of a particular cell group can be transmitted through a Pcell if the particular cell group is a Pcell group having the Pcell and can be transmitted through the Acell of the Scell group if the particular cell group is an Scell group.
Claims6
A method for transmitting uplink control information (UCI) by a user equipment (UE), the method comprising:
- receiving information on whether a simultaneous physical uplink control channel (PUCCH) and physical uplink shared channel (PUSCH) transmission on a primary cell group is allowed and information on whether the simultaneous PUCCH and PUSCH transmission on a secondary cell group is allowed;
- and
- transmitting at least a first UCI for the primary cell group only, a second UCI for the secondary cell group only, or a third UCI for both of the primary and secondary cell groups,
- wherein the primary cell group includes a primary cell among a plurality of cells for the UE, and the secondary cell group includes one or more secondary cells not belonging to the primary cell group among the plurality of cells,
- wherein the first UCI and the second UCI are transmitted through a first PUSCH configured on the primary cell group and a second PUSCH configured on the secondary cell group, respectively, when the simultaneous PUCCH and PUSCH transmission is allowed in at least one of the primary and secondary cell groups, and
- wherein the third UCI is transmitted through only one of the first and second PUSCHs when the simultaneous PUCCH and PUSCH transmission is not allowed in any one of the primary and secondary cell groups.

- control the transceiver to receive information on whether a simultaneous physical uplink control channel (PUCCH) and physical uplink shared channel (PUSCH) transmission on a primary cell group is allowed and information on whether the simultaneous PUCCH and PUSCH transmission on a secondary cell group is allowed;
- and
- control the transceiver to transmit at least a first UCI for the primary cell group only, a second UCI for the secondary cell group only, or a third UCI for both of the primary and secondary cell groups,
- wherein the primary cell group includes a primary cell among a plurality of cells for the UE, and the secondary cell group includes one or more secondary cells not belonging to the primary cell group among the plurality of cells,
- wherein the first UCI and the second UCI are transmitted through a first PUSCH configured on the primary cell group and a second PUSCH configured on the secondary cell group, respectively, when the simultaneous PUCCH and PUSCH transmission is allowed in at least one of the primary and secondary cell groups, and
- wherein the third UCI is transmitted through only one of the first and second PUSCHs when the simultaneous PUCCH and PUSCH transmission is not allowed in any one of the primary and secondary cell groups.
